Vegetation cover and radiocarbon dates of palsa and peat plateaus in the Hudson Bay Lowlands

The Holocene development of a treed palsa bog and a peat plateau bog, located near the railroad to Churchill in the Hudson Bay Lowlands of northeastern Manitoba, was traced using peat macrofossil and radiocarbon analyses. Both sites first developed as wet rich fens through paludification of forested uplands around 6800 cal. yr BP. Results show a 20th-century age for the palsa formation and repeated periods of permafrost aggradation and collapse at the peat plateau site during the late Holocene. This timing of permafrost dynamics corroborates well with that inferred from previous studies on other permafrost peatlands in the same region. The developmental history of the palsa and peat plateau bogs is similar to that of adjacent permafrost-free fens, except for the specific frost heave and collapse features associated with permafrost dynamics. Permafrost aggradation and degradation is ascribed to regional climatic, local autogenic and other factors. Particularly the very recent palsa development can be assessed in terms of climatic changes as inferred from meteorological data and surface hydrological changes related to construction of the railroad. The results indicate that cold years with limited snowfall as well as altered drainage patterns associated with infrastructure development may have contributed to the recent palsa formation.

Fertility and rural electrification in Bangladesh

We use a panel dataset from Bangladesh to examine the relationship between fertility and the adoption of electricity with the latter instrumented by infrastructure development and the quality of service delivery. We find that the adoption of electricity reduces fertility, and this impact is more pronounced when the household already has two or more children. This observation can be explained by a simple household model of time use, in which adoption of electricity affects only the optimal number of children but not necessarily current fertility behavior if the optimal number has not yet been reached.

Determinants of inbound tourists in Cambodia : a dynamic panel data approach

Understanding the determinants of tourism demand is crucial for the tourism sector. This paper develops a dynamic panel model to examine the determinants of inbound tourists to Siem Reap airport, Phnom Penh airport, and land and waterway borders in Cambodia. Consistent with the consumer theory of tourism consumption, a 10% increase in the origin country GDP per capita is predicted to increase the number of tourist visits to Siem Reap airport by 5.8%. A 10% increase in the real exchange rate between the origin country and Cambodia is predicted to decrease the number of tourist visits by 0.89%. In contrast, the number of foreign tourists in a previous period has little effect on the number of foreign tourists in the current period. Additionally, the determinants are different by the mode of entry to Cambodia.

Forecasting inbound tourists in Cambodia

Forecasting tourism demand is crucial for management decisions in the tourism sector. Estimating a vector autoregressive (VAR) model for monthly visitor arrivals disaggregated by three entry points in Cambodia for the years 2006–2015, I forecast the number of arrivals for years 2016 and 2017. The results show that the VAR model fits well with the data on visitor arrivals for each entry point. Ex post forecasting shows that the forecasts closely match the observed data for visitor arrivals, thereby supporting the forecasting accuracy of the VAR model. Visitor arrivals to Siem Reap and Phnom Penh airports are forecast to increase steadily in future periods, with varying fluctuations across months and origin countries of foreign tourists.

Conservación de plantas regeneradas in vitro y análisis de la variación somaclonal de Cinchona officinalis, Linneo

Cinchona officinalis (Rubiaceae), especie endémica del Valle de Loja, ubicado en la región sur del Ecuador, es un recurso forestal de importancia medicinal y ecológica, además la especie ha sido catalogada como planta nacional y es un ícono de la región sur por su aporte a la farmacopea mundial. Esta especie, entre los siglos XVII-XIX sufrió una gran presión en sus poblaciones debido a la extracción masiva de la corteza para la cura del paludismo. Aunque la actividad extractiva generó grandes ingresos a la Corona Española y a la región Sur del Ecuador, ésta fue poco o nada sustentable ecológicamente, provocando la desaparición de la especie en muchos sitios de la provincia, pues, en su momento, no se consideraron alternativas de recuperación de las poblaciones naturales. Actualmente la extracción y consumo de la corteza en la zona de origen es baja o nula, sin embargo esta zona enfrenta nuevas amenazas. La deforestación a causa de proyectos de desarrollo en infraestructuras, la práctica de actividades agrícolas y de ganadería, y los efectos del cambio climático han ocasionado, en estos últimos años, la fragmentación de los ecosistemas. La mayoría de los bosques del sur del Ecuador se han convertido en parches aislados (los bosques en los que se distribuye C. officinalis no son la excepción) siendo esta la principal causa para que la especie se encuentre en estado de amenaza. Los individuos de la especie tienen una alta capacidad de rebrote y producen semillas durante todo el año; sin embargo la capacidad germinativa y la tasa de sobrevivencia son bajas, además de estas dificultades la especie requiere de la asociación con otras especies vegetales para su desarrollo, lo cual ha limitado su distribución en pequeños parches aislados. Con esta problemática, la recuperación natural de las poblaciones es una necesidad evidente. Varios trabajos y esfuerzos previos se han realizado a nivel local: i. Identificación de la distribución actual y potencial; ii. Determinación de la fenología y fructificación iii. Programas de educación ambiental, iv. Análisis moleculares para determinar la diversidad genética. v. Ensayos de propagación vegetativa; y otras acciones de tipo cultural. No obstante, el estado de conservación y manejo de las poblaciones naturales no ha mejorado significativamente, siendo necesaria la aplicación de estrategias integradas de conservación in situ y ex situ, que permitan la recuperación y permanencia de las poblaciones naturales a largo plazo. El presente trabajo tiene como fin dar alternativas para el cultivo de tejidos in vitro de Cinchona officinalis centrados en la propagación masiva a partir de semillas, análisis de la fidelidad genética y alternativas de conservación de tejidos. Los objetivos específicos que se plantean son: i. Analizar el proceso de germinación y proliferación in vitro. ii. Evaluar la estabilidad genética en explantes cultivados in vitro, mediante marcadores ISSR. iii. Establecer protocolos de conservación in vitro mediante limitación del crecimiento y criopreservación de segmentos nodales y yemas. Los resultados más significativos de esta investigación fueron: i. El desarrollo de protocolos eficientes para mejorar los porcentajes de germinación y la proliferación de brotes en explantos cultivados in vitro. Para evaluar el efecto de los fenoles sobre la germinación, se determinó el contenido total de fenoles y el porcentaje de germinación en semillas de C. officinalis comparados con una especie de control, C. pubescens. Para inducir a proliferación, se utilizaron segmentos nodales de plántulas germinadas in vitro en medio Gamborg (1968) suplementado con diferentes combinaciones de reguladores de crecimiento (auxinas y citoquininas). Los resultados obtenidos sugieren que el contenido de compuestos fenólicos es alto en las semillas de C. officinalis en comparación con las semillas de C. pubescens. Estos fenoles pueden eliminarse con peróxido de hidrógeno o con lavados de agua para estimular la germinación. La formación de nuevos brotes y callos en la mayoría de las combinaciones de reguladores de crecimiento se observó en un período de 45 días. El mayor porcentaje de proliferación de brotes, formación de callos y presencia de brotes adventicios se obtuvo en medio Gamborg (B5) suplementado con 5.0 mg/l 6-bencil-aminopurina y 3.0 mg/l de ácido indol-3-butírico. ii. La evaluación de la fidelidad genética de los explantes obtenidos con distintas combinaciones de reguladores de crecimiento vegetal y diversos subcultivos. Se realizó el seguimiento a los explantes obtenidos de la fase anterior, determinando el índice de multiplicación y analizando la fidelidad genética de los tejidos obtenidos por las dos vías regenerativas: brotación directa y regeneración de brotes a partir de callos. Este análisis se realizó por amplificación mediante PCR de las secuencias ubicadas entre microsatélites-ISSR (Inter simple sequence repeat). El medio Gamborg (B5) con 3.0 mg/l de AIB y 5.0 mg/l de BAP usado como medio de inducción en la primera etapa de cultivo generó el mayor índice de proliferación (11.5). Un total de 13 marcadores ISSR fueron analizados, 6 de éstos fueron polimórficos. El mayor porcentaje de variación somaclonal fue inducido en presencia de 1.0 mg/l 2,4-D combinado con 0.2 mg/l Kin con un 1.8% en el segundo sub-cultivo de regeneración, la cual incrementó a 3.6% en el tercer sub-cultivo. Todas las combinaciones con presencia de 2,4-D produjeron la formación de callos y presentaron variación genética. Por su parte la fidelidad genética se mantuvo en los sistemas de propagación directa a través de la formación de brotes a partir de meristemos preformados. iii. El establecimiento de protocolos de conservación in vitro y crioconservación de segmentos nodales y yemas. Para la conservación limitando el crecimiento, se cultivaron segmentos nodales en los medios MS y B5 en tres concentraciones de sus componentes (25, 50 y 100%); y en medio B5 más agentes osmóticos como el manitol, sorbitol y sacarosa en diferentes concentraciones (2, 4 y 8%); los cultivos se mantuvieron por 12 meses sin subcultivos. Para el establecimiento de protocolos para la crioconservación (paralización del metabolismo) se usaron yemas axilares y apicales a las cuales se les aplicaron los métodos de encapsulación-deshidratación y vitrificación. La efectividad de los protocolos usados se determinó en función de la sobrevivencia, reducción del crecimiento y regeneración. Los resultados obtenidos en este apartado reflejan que un crecimiento limitado puede mantener tejidos durante 12 meses de almacenamiento, usando medio B5 más manitol entre 2 y 8%. En los protocolos de crioconservación, se obtuvo el mayor porcentaje de recuperación tras la congelación en NL en el tratamiento control seguido por el método crioprotector de encapsulación-deshidratación. Este trabajo brinda alternativas para la propagación de C. officinalis bajo condiciones in vitro, partiendo de material vegetal con alta diversidad genética. El material propagado puede ser fuente de germoplasma para la recuperación y reforzamiento de las poblaciones naturales así como una alternativa de producción para las comunidades locales debido a la demanda actual de corteza de la zona de origen para la elaboración de agua tónica. ABSTRACT Cinchona officinalis (Rubiaceae) is endemic to the Loja Valley, located in the southern area of Ecuador. The importance of this plant as medical and ecological resource is so great that it has been designated as the national flower and is an icon of the southern region for its contribution to the world pharmacopoeia. Between XVII-XIX centuries its population suffered great reduction due to massive harvesting of the bark to cure malaria. Although extraction activity generated large revenues to the Spanish Crown and the southern region of Ecuador, this was not ecologically sustainable, causing the disappearance of the species in many areas of the province, because during that time alternatives to prevent extinction and recover natural populations were not taken in account. Currently the extraction and consumption of bark in the area of origin is almost absent, but this species faces new threats. Deforestation due to infrastructure development, the practice of farming and ranching, and the effects of climate change had led to the fragmentation of ecosystems during the recent years. Most of the forests of southern Ecuador have become isolated patches, including those where C. officinalis is diffused. The lack of suitable habitat is today the main threat for the species. The species has a high capacity for regeneration and produces seeds throughout the year, but the germination rate is low and the growth is slow. In addition, the species requires the association with other plant species to develop. All these factors had limited its distribution to small isolated patches. The natural recovery of populations is essential to face this problem. Several studies and previous efforts had been made at local level: i. Identification of current and potential distribution; ii. Phenology determination. iii. Environmental education programs, iv. Molecular analisis to determine the genetic diversity. v. Testing of vegetative propagation; and other actions of cultural nature. Despite these efforts, the state of conservation and management of natural populations has not improved significantly. Implementation of integrated in situ and ex situ conservation strategies for the recovery and permanence of long-term natural populations is still needed. This work aims to provide alternatives for in vitro culture of tissue of Cinchona officinalis focused on mass propagation from seeds, genetic fidelity analysis and tissue conservation alternatives. The specific aims are: i. Analyze the process of germination and proliferation in vitro. ii. To evaluate the genetic stability of the explants cultured in vitro by ISSR markers. iii. Establish protocols for in vitro conservation by limiting growth and cryopreservation of nodal segments and buds. The most significant results of this research were: i. The development of efficient protocols to improve germination rates and proliferation of buds in explants cultured in vitro. To study the effect of phenols on germination, the total phenolic content and percentage germination was measured in C. officinalis and in a control species, C. pubescens, for comparison. The content of phenolic compounds in C. officinalis seeds is higher than in C. pubescens. These phenols can be removed with hydrogen peroxide or water washes to stimulate germination. To analyze the regeneration, we used nodal explants from seedlings germinated in vitro on Gamborg medium (1968) supplemented with different combinations of growth regulators (auxins and cytokinins) to induce proliferation. The formation of new shoots and calluses was observed within a period of 45 days in most combinations of growth regulators. The highest percentage of shoot proliferation, callus formation and adventitious buds were obtained in B5 medium supplemented with 5.0 mg/l 6-benzyl-aminopurine and 3.0 mg/l indole-3-butyric acid. ii. Evaluating genetic fidelity explants obtained with various combinations of plant growth regulators and different subcultures. The genetic fidelity was analyzed in tissues obtained by the two regenerative pathways: direct sprouting and shoot regeneration from callus. This analysis was performed by PCR amplification of the sequences located between microsatellite-ISSR (Inter Simple Sequence Repeat). Among a total of 13 ISSR markers analyzed, 6 were polymorphic. The highest percentage of somaclonal variation was induced in the presence of 1.0 mg/l 2,4-D combined with 0.2 mg/l Kin with 1.8% in the second round of regeneration, and increased to 3.6% in the third round. The presence of 2,4-D induced genetic variation in all the combinations of growth regulators. Meanwhile genetic fidelity remained systems propagation through direct shoot formation from meristems preformed. iii. Establishing conservation protocols in vitro and cryoconservation of nodal segments and buds. For medium-term conservation (limited growth) nodal segments were cultured in MS and B5 media at three concentrations (25, 50 and 100%); we tested B5 medium with different concentrations of osmotic agents such as mannitol, sorbitol and sucrose (2, 4 and 8%); cultures were maintained for 12 months with regular subculturing. To establish protocols for cryoconservation (cessation of metabolism) different methods of encapsulation-dehydration and vitrification were applied to axillary and apical buds. The effectiveness of the used protocols is determined based on the survival, growth and regeneration success. The results show that these tissues can be maintained in storage for 12 months, using B5 medium plus mannitol between 2 and 8%. The cryoconservation protocol with highest percentage of recovery was obtained by contral treatment, followed by freezing in NL with encapsulation-dehydration method. This work provides alternatives for the propagation in vitro of C. officinalis, starting from plant material with high genetic diversity. The obtained material represents a source of germplasm to support the recovery and strengthening of natural populations as well as a creation of alternative sources for local communities due to the current demand of bark for the preparation of tonic water.

Turismo y desarrollo sostenible en la provincia de Samaná, República Dominicana

The eastern ‘partnership’ of gas. Gazprom and CNPC strike a deal on gas supplies to China. OSW COMMENTARY No. 139, 2014-06-16

The CEOs of Gazprom and China’s CNPC signed a contract concerning Russian gas supplies to China on 21 May 2014 in Shanghai. The contract had been under negotiation for many years and was signed in the presence of the two countries’ presidents. Under this 30-year deal, ultimately 38 billion m3 of natural gas will be exported annually from eastern Siberian fields (Chayandinskoye and Kovyktinskoye) via the Power of Siberia pipeline planned for construction in 2015–2019. The lengthy negotiation process (initial talks regarding this issue began back in the 1990s), the circumstances surrounding the signing of the contract (it was signed only on the second day of Vladimir Putin’s visit to Shanghai, and the Russian president’s personal engagement in the final phase of the talks turned out to be a key element) and information concerning the provisions of the contract (the clause determining the contract price has not been revealed) all indicate that the terms of the compromise are more favourable for China than for Russia. This contract is at present important to Russia mainly for political reasons (it will use the future diversification of gas export routes as an instrument in negotiations with the EU). However, the impact of this instrument seems to be limited since supplies cannot be redirected from Europe to Asia. It is unclear whether the contract will bring the anticipated long-term economic benefits to Gazprom. The gas price is likely to remain at a level of between US$350 and US$390 per 1000 m3. Given the high costs of gas field operation and production and transport infrastructure development, this may mean that supplies will be carried out at the margin of profitability. The Shanghai contract does not conclude the negotiation process since a legally binding agreement on gas pipeline construction has not been signed and not all of the financial aspects of the project have been agreed upon as yet (such as the issue of possible Chinese prepayments for gas supplies).

Perspectives in Resource Management and Climate Change Adaptation in the Southern and Eastern Mediterranean. MEDPRO Policy Paper No. 6, March 2013

This policy paper focuses on the sustainable management of some key natural resources in southern and eastern Mediterranean countries (SEMCs) under climate change and anthropogenic pressures. In a business-as-usual and even more so in a failed cooperation scenario, water resources, ecosystems and biodiversity in the region are under stress, with negative consequences for agriculture, food security, tourism and development. However, proper adaptation strategies are shown to be effective in reconciling resource conservation with GDP, trade and population growth. These need be implemented in different ways: technological, institutional, behavioural; and at different levels: regional, national and international. There is ample room for fruitful cooperation between the EU and SEMCs in this area, which can take the form of EU direct financial and technical support when resources in SEMCs are scarce, and of multilateral and bilateral cooperation programmes to improve resource efficiency. The EU could also take on the role of coordinating these different bilateral actions and, at the same time, support SEMCs to establish a structured programme focused on the communication and dissemination of emerging best practices.

Energy in the Eastern Mediterranean: promise or peril? Egmont Paper No. 65, May 2014

From the Introduction. In order to address the different challenges and opportunities on energy cooperation in the Eastern Mediterranean Region and Levant Basin, EGMONT – The Royal Institute for International Relations of Belgium – together with the Atlantic Council, and supported by H. E. Belgian Minister for Foreign Affairs Didier Reynders, opened an expert dialogue in 2013 in order to look at how the management of the new energy resources could act as a vector of cooperation instead of conflict between the concerned countries. The activities have targeted finding new possibilities for cooperation on political and security challenges, energy infrastructure development, the regulatory and legal framework, environmental concerns, and bilateral and regional structures, in a manner that enhances stability and security in the region, increases European energy security, contributes to rather than hinders a comprehensive Cyprus settlement, and promotes wider regional cooperation.

A Cultura Caiçara do Litoral Norte Paulista mostrada na revista Beach&Co Estereótipos do caiçara das cidades de Caraguatatuba, São Sebastião, Ubatuba e Ilhabela em um veículo regional impresso

Estudo dos estereótipos que a revista regional Beach&Co fez do caiçara - povo nativo que mantém uma cultura relacionada ao mar e a mata nas cidades de Caraguatatuba, São Sebastião, Ubatuba e Ilhabela, no Litoral Norte Paulista. Aplicou-se uma metodologia de caráter híbrido que mesclou os Estudos Culturais com base nas obras de Douglas Kellner, Stuart Hall e Raymond Williams com a Análise de Discurso nas obras de Dominique Maingueneau, Eni Orlandi, Patrick Charaudeau e Audre Alberguine. Também foram resgatados os estudos da Cultura Caiçara feitos por Carlos Diegues, Gioconda Mussolini, Emilio Willems, e por fim redefiniu-se o gênero jornalístico Reportagem e contextualizou-se o Jornalismo Regional de Revista. Posteriormente, analisou-se a primeira década da revista Beach&Co, totalizando 120 edições publicadas de janeiro de 2002 a junho de 2012, no qual foram mostradas as diversas abordagens que a publicação fez do caiçara, bem como a evolução da própria revista nos aspectos editoriais, comercial e de design gráfico. Em seguida, selecionou-se 23 reportagens nas editorias de turismo, gastronomia, esportes e outras relacionadas à Cultura Caiçara, que tiveram seus discursos semânticos e os elementos valorativos de linguagens analisados. Nas conclusões, constatou-se que a cobertura jornalística da Beach&Co privilegia as áreas do turismo e do desenvolvimento do Litoral Norte e Baixada Santista; que a revista passou por readaptações e esquematismos dominantes na produção jornalística e encontrou mercado nas especificidades do Litoral Paulista; a Beach&Co se consolidou como uma revista regional profissional, de qualidade e criativa, distante do amadorismo, do bairrismo e da mimetização simplista; apesar de muitas vezes ter usado o caiçara para adjetivar os aspectos turísticos e gastronômicos do Litoral Norte, a revista trabalhou a produção simbólica do caiçara de forma ampla e retratou vários aspectos da Cultura Caiçara, reforçando o poder desta revista regional, como retroalimentando os sotaques do Litoral Paulista nas demais regiões do país onde a publicação também é lida.

GUIDE@HAND: Digital GPS Based Audio Guide that Brings the Past to Life

In the digital age the internet and the ICT devices changed our daily life and routines. It means we couldn't live without these services and devices anywhere (work, home, holiday, etc.). It can be experienced in the tourism sector; digital contents become key tools in the tourism of the 21st century; they will be able to adapt the traditional tourist guide methodology to the applications running on novel digital devices. Tourists belong to a new generation, an "ICT generation" using innovative tools, a new info-media to communicate. A possible direction for tourism development is to use modern ICT systems and devices. Besides participating in classical tours guided by travel guides, there is a new opportunity for individual tourists to enjoy high quality ICT based guided walks prepared on the knowledge of travel guides. The main idea of the GUIDE@HAND service is to use reusable, and create new tourism contents for an advanced mobile device, in order to give a contemporary answer to traditional systems of tourism information, by developing new tourism services based on digital contents for innovative mobile applications. The service is based on a new concept of enhancing territorial heritage and values, through knowledge, innovation, languages and multilingual solutions going along with new tourists‟ “sensitiveness”.

Cultural cooperation, institution building, and metropolitan governance in decentralizing Indonesia

The institutional turn in metropolitan governance has been influenced to a considerable degree by a rational choice approach, which views metropolitan governance as essentially created by local actors to reduce the transaction costs of inter-jurisdictional public-service provision. Another influential theoretical route follows a historical approach, which emphasizes the role of the state structure in producing formal institutions to enable governance at the regional level. Both approaches tend to be formalistic, simplistic and deterministic in nature, thus neglecting the dynamic interactions between the actors and their more informal, intangible, yet more basic, legitimate institutions, such as culture. This article examines the dynamic role of culture in metropolitan governance building in the context of decentralizing Indonesia. The analysis focuses on ‘best-practice’ experiences of metropolitan cooperation in greater Yogyakarta, where three neighbouring local governments known as Kartamantul have collaboratively performed cross-border infrastructure development to deal with the consequences of extended urbanization. We draw on sociological institutionalism to argue that building this metropolitan cooperation has its roots in the capacity of the actors to use and mobilize culture as a resource for collaborative action.

Heatwave planning: the role of the community in co-producing resilience

Drawing on a thematic analysis of relevant policy documents, the aim of this paper is to comment on an apparent disconnect between two associated contemporary UK policy areas: planning for heatwaves and community resilience. Regional and national policy documents that plan for heatwaves in the UK tend to focus on institutional emergency responses and infrastructure development. In these documents, although communities are mentioned, they are understood as passive recipients of resilience that is provided by active institutions. Meanwhile, contemporary discussion about community resilience highlights the potential for involving communities in planning for and responding to emergencies (although the concept is also the subject of critique). Within this context, the paper proposes that – through engagement with the ‘community resilience’ policy agenda and its critique – effort should be made to articulate and realise greater participation by individuals, and voluntary and community sector groups in heatwave preparation, planning and response.

Renar och vindkraft II : Vindkraft i drift och effekter på renar och renskötsel

Utbyggnaden av vindkraft inom renskötselområdet har ökat markant det senaste decenniet, trots att kunskapen om påverkan av vindkraftsetableringar ännu inte är fullt utredd och dokumenterad. I den här rapporten beskriver vi framförallt hur vindkraftparker i driftsfas påverkar renarna och renskötseln i tre olika områden. I Malå sameby har vi studerat kalvningsområdet kring Storliden och Jokkmokkslidens vindkraftparker. I Vilhelmina Norra sameby har vi studerat vinterbetesområdet kring Stor-Rotlidens vindkraftpark, samt Lögdeålandets betesområde med Gabrielsbergets vindkraftpark som används av Byrkije reinbetesdistrikt från Norge. För att få en helhetsbild av hur renarna använder sitt betesområde är det viktigt att studera renarnas betes- och förflyttningsmönster långsiktigt och över hela deras betesområde och inte bara inom det lokala området nära parken. Det är också viktigt att ta hänsyn till att renarnas betesutnyttjande skiftar från år till år och mellan olika årstider beroende på väderlek och andra yttre förutsättningar. Vi vill också understryka vikten av att kombinera den traditionella kunskapen från renskötarna med vedertagna vetenskapliga analysmetoder för att besvara de frågor som är viktiga för att kunna bedriva en hållbar renskötsel. Vi har undersökt renarnas användning av områdena genom att utföra spillningsinventeringar under åren 2009-2015 (endast i Malå sameby), och genom att följa renar utrustade med GPS-halsband under åren 2005-2015. Datat är insamlat före och under byggfas och under driftsfas (för Gabrielsberget finns GPS-data endast för driftsfasen). Vi har analyserat data genom att utveckla statistiska modeller för val av betesområde för varje område där vi har beräknat hur renarna förhåller sig till vindkraftparksområdet före, under och efter byggnation, och på Gabrielsberget när parken varit avstängd under 40 dagar och under drift vid olika renskötselsituationer. Genom intervjuer, möten och samtal, samt information från Gabrielsbergets vindkraftparks kontrollprogram, har vi tagit del av renskötarnas erfarenheter av hur renarnas beteende, och därmed även renskötseln, påverkats av vindkraftsutbyggnaden i respektive område. Våra resultat visar att renarna både på kalvnings- och på vinterbetesområden påverkas negativt av vindkraftsetableringarna (Tabell a). Renarna undviker att beta i områden där de kan se och/eller höra vindkraftsverken och föredrar att vistas i områden där vindkraftverken är skymda. I kalvningsområdet i Malå ökade användningen av skymda områden med 60 % under driftsfas. I vinterbetesområdet på Gabrielsberget, när renarna utfodrades i parken och kantbevakades intensivt för att stanna i parkområdet under driftsfas, ökade användningen av skymda områden med 13 % jämfört med när de inte var utfodrade och fick ströva mer fritt. Resultaten visar också att renarna minskar sin användning av området nära vindkraftparkerna. I kalvningslandet i Malå minskar renarna sin användning av områden inom 5 km från parkerna med 16-20 %. Vintertid vid Gabrielsbergets vindkraftpark undvek renarna parken med 3 km. Våra resultat visar även att renarnas betesro minskar inom en radie på 4 km från vindkraftparkerna under kalvningsperioden och tiden därefter i jämförelse med perioden före byggfas. Exakta avstånd som renarna påverkas beror på förutsättningarna i respektive område, exempelvis hur topografin ser ut eller om området är begränsat av stängsel eller annan infrastruktur. Förändringarna i habitatutnyttjande i våra studieområden blev tydligare när parkerna var centralt belägna i renarnas betesområde, som i kalvningsområdet i Malå eller i vinterbeteslandet på Gabrielsberget, medan det inte var lika tydliga effekter kring Stor-Rotlidens park, som ligger i utkanten av ett huvudbetesområde. Oftast är snöförhållandena bättre ur betessynpunkt högre upp i terrängen än nere i dalgångarna, på grund av stabilare temperatur, vind som blåser bort snötäcket och mer variation i topografin. Därför kan etablering av vindkraftparker i höglänta områden försämra möjligheten att använda sådana viktiga reservbetesområden under vintrar med i övrigt dåliga snöförhållanden, vilka blir allt vanligare i och med klimatförändringarna. Våra resultat tyder inte direkt på att renarna påverkats negativt under dåliga betesvintrar men fler år av studier behövs för att ytterligare klargöra hur vindkraft påverkar renarna under dessa vintrar. Våra studier har visat att etablering av vindkraft har konsekvenser för renskötseln under både barmarkssäsongen och under vintern, men effekterna förmodas få störst inverkan inom vinterbetesområdet där det är svårt att hitta alternativa betesområden för renarna. Under sommaren är betestillgången oftast mindre begränsad och renarna kan lättare hitta alternativa områden. En direkt konsekvens av Gabrielsbergets vindkraftpark som är placerad mitt i ett vinterbetesområde har blivit att renarna behöver tillskottsutfodras och bevakas intensivare för att de inte ska gå ut ur området. När den naturliga vandringen mellan olika betesområden störs för att renarna undviker att vistas i ett område kan det leda till att den totala tillgången till naturligt bete minskar och att man permanent måste tillskottsutfodra, alternativt minska antalet renar. Annan infrastruktur som vägar och kraftledningar påverkar också renarna. Vid Storliden och Jokkmokksliden och vid Stor-Rotliden där data samlats in innan vindkraftparken uppfördes visar våra resultat att renarna undviker de omkringliggande landsvägarna redan innan parkerna etablerades. Vid Stor-Rotliden ökar dock renarna användningen av områden nära vägarna efter att parken är byggd. På Gabrielsberget, där vi endast har data under drifttiden, är renarna närmare vägarna (även stora vägar som E4) när renskötarna minskar på kantbevakningen för att inte hålla renarna nära parken. Detta ökar naturligtvis risken för trafikolyckor och innebär att renskötarna måste bevaka dessa områden intensivare. Sist i rapporten presenterar vi förslag till åtgärder som kan användas för att underlätta arbetet för renskötseln om det är så att en vindkraftpark redan är byggd. Några exempel på åtgärder som är direkt kopplat till parken är att stänga av vägarna in i vindkraftparken för att förhindra nöjeskörning med skoter och bil under den tiden renarna vistas i området samt tät dialog mellan vindkraftsbolag och sameby angående vinterväghållningen av vägarna till och inom vindkraftparken. Andra mer regionala åtgärder för att förbättra förutsättningarna för renskötselarbetet på andra platser för samebyn, kan vara att sätta stängsel längst större vägar och järnvägar (t.ex. E4:an eller stambanan) i kombination med strategiskt utplacerade ekodukter. Detta för att underlätta och återställa möjligheterna till renarnas fria strövning och renskötarnas flytt av renar mellan olika betesområden.   

Can open access repositories and peer-reviewed journals coexist?

It is often assumed that open access repositories and peer-reviewed journals are in competition with each other and therefore will in the long term be unable to coexist. This paper takes a critical look at that assumption. It draws on the available evidence of actual practice which indicates that coexistence is possible at least in the medium term. It discusses possible future models of publication and dissemination which include open access, repositories, peer review and journals. The paper suggests that repositories and journals may coexist in the long term but that both may have to undergo significant changes. Important areas where changes need to occur include: widespread deployment of repository infrastructure, development of version identification standards, development of value-added features, new business models, new approaches to quality control and adoption of digital preservation as a repository function.
